Question

我的目标是使用EC2发现在AWS中创建弹性搜索群集。

我有3个实例，每个实例都运行elasticsearch。我为每个实例提供了一个IAM角色，允许他们描述ec2数据。每个实例都在安全组“sec-group-elasticsearch”

中

节点启动但没有找到对方（下面的日志）。

我可以使用私有DNS和端口9300从一个节点telnet到另一个节点。

参考
例如。来自节点A-> B的telnet工作，B-＆gt; A工作。

telnet ip-xxx-xxx-xx-xxx.vpc.fakedomain.com 9300

每个实例的iam角色

{
    "Statement": [
        {
            "Action": [
                "ec2:DescribeInstances"
            ],
            "Effect": "Allow",
            "Resource": [
                "*"
            ]
        }
    ],
    "Version": "2012-10-17"
}

Answer 1

您的elasticsearch.yml配置文件中有一个小错字：

discovery: ec2

应为：

discovery.type: ec2

AWS elasticsearch EC2 Discovery，无法找到其他节点
